ktvu's tara moriarty who is in san jose with what is going on right now. tara? >> reporter: sabotage or stealing copper. these are some theories being floated around out here. regarding what happened this morning, vandalism to the pg&e substakes and also some -- sub station and also vandalism down the road on monterey street here. authorities say some fiber cables were cut shutting down cell and landline service for thousands of at&t customers in the san jose and gilroy area. that means 911 calls were affected, although we don't know the extent of the problem just yet. this video shows the scene headed northbound on monterey. there's a fleet of pg&e and at&t service vehicles. this is the area from which sheriff's deputies say people heard 30 to 40 gunshots around 1:45 this morning. >> the substation has vandalized earlier this morning. there was damage done.

there was an oil leak to the substation and we're currently working to assess the situation. >> reporter: pg&e reported a breach in one of the fences. our video shows oil spewing out of at least one transformer at the metcalf substakes. authorities -- sub station but authorities won't say if bullets struck it but that's what it looks like. >> there's no danger of any explosions. there's no danger to the public at this point. right now we're just trying to clean up the hazmat situation and then we'll conduct a criminal investigation. >> reporter: now, in the meantime, a flex alert has been urged for businessessage areas in the san jose area to conserve electricity now following heavy damage to the metcalf substation. coming up at 5:00, john fouler will do some digging to see if we can get any more questions

answered about what's going on. we've seen a huge number of service vehicles go in and out of this area all morning long. so if there's any more information, we will, of course, bring it to you in our later broadcast. i'm tara moriarty, ktvu channel 2 news. >> thank you, tara, for the update. to our other top story today -- the boston marathon bombing attacks. three people were killed. more than 170 others injured in yesterday's double blast. at least 17 of those people we understand are critically injured. now, today investigators released new details of how the bombs were made, say they were fashioned out of pressure cookers and packed with shards of metal, nails and ball bears. today president obama -- ball bearings. today president obama called the attacks heinous and promised justice. the president said the fbi is treating the attacks as an act of terrorism. >> any time bombs are used to

target innocent civilians. , it's an act of -- civilians, it's an act of terror. we don't know who carried out this attack or why, whether it was planned and executed by a terrorist organization, foreign or domestic, or was the act of a mal lev lent -- malevolent individual. that's what we don't know. we're at the beginning of our investigation. we'll take time to follow every lead and determine what happened. but we will find out. >> the president ordered flags at the white house and all government buildings to be flown at half-staff in honor of the bombing victims. tips are pouring into the fbi as the joint terrorism task force pieces together what happened and why. ktvu sea 's alex savidge is in our newsroom with more. >> well, "the associated press" reported the two bombs were made out of pressure cookers

packed with metal, ball bearings and all of this designed to cause the most serious injuries. federal investigators are interviewing a variety of people as they try to figure out who designed and detonated those devices. [screaming] >> a camera attached to a marathon runner captured this view of one of the explosions. two bombs went off seconds apart near the finish line of the boston marathon. a little while ago, one injured spectator spoke from the hospital. >> you're mad because why? why do people do this, whether for religion or politics, whatever the case may be, it's not worth it. >> reporter: according to one report, explosives were packed into six-liter pressure cookers, placed in duffel backs and left on the ground. investigators say -- bags and left on the ground. investigators say no one is in custody. but they are working quickly. >> this will be a worldwide

investigation. we will go to the ends of the earth to identify the subject or subjects responsible for this despicable crime. >> reporter: overnight authorities searched this apartment in the city of revere outside boston but talk about what they -- but would not talk about what they found. the fbi is urging everyone to turn over videos and pictures that may offer clues to who set off the bombs. the bombs killed three people, including martin, this 8-year- old. doctors said they removed pellets and nails from many patients. >> a variety of sharp objebllths we found in the bod -- objects we found in the bodies. probably this bomb had multiple metallic fragments in there. >> reporter: doctors said any shrapnel will be turned over to investigators who are trying to

understand how these crude explosive devices were constructed and what was used to set them off along the crowded marathon route. >> within the last half-hour, authorities have identified a second victim kill yesterday as crystal campbell of massachusetts. so far, nobody has claimed responsibility for the bombings and the fbi now trying to figure out if this attack was carried out by an international organization, a domestic group or someone acting alone. we're live this afternoon in the newsroom, alex savidge, ktvu channel 2 news. >> thank you, alex. increased security measures are in place in the nation's capitol. the secret service has expanded its perimeter around the white house putting up yellow tape to keep people away. increased security has also been reported along the metro subway station and along the routes of the emans dation day parade which went on -- he emancipation day parade which went on. officers are walking around

with their dogs checking garbage cans. now, there are still many questions left unanswered. right now we want to take you live to boston where jennifer davis is standing by. jennifer, what can you tell us about what's happening now at the scene of the explosions? >> reporter: well, they are certainly sifting through every bit of evidence and that's where the details have come about the pressure cookers. they found shredded pieces of those kitchen devices that has given them a great idea of how the bombs were made. we've been getting details from the doctors at the office who gave those clues as well and said as we were seeing our patients as we were helping them through our surgeries we were finding this metal and the information is coming from different areas. there is the front but with over -- there's the investigation but with over 170 victims, there's help for them. some have had their legs

amputated. there are two fronts as this town tries to recover from what happened here yesterday. >> certainly the investigation continues this morning. have -- we listened to the fbi press conference this morning where they really said no one is in custody. no talk about a motive yet. have you heard any updates on that? >> reporter: no. they've really been very consistent in saying there's no motive, that there's no -- there's no suspect. they don't know if this is a domestic or international organization. no one has taken credit for this as sometimes happens after something like this. they are going over the threats made for the last 30 days. just up the road here where all of this unfolded, because both of those bombs detonated they have to pick through to find

pieces. there had been initial reports that maybe there was some undetonated bombs, that turned out not to be true. they only have to work with all of the pieces that they are able to find at the crime scene. >> we understand that that could be a crime scene for several days. jennifer davis there live in boston. thank you for the update. back here in the bay area, heightened security is inevitable at this year's beta breakers race a month away. organizers said the safety and security of race participants and spectators will be their first priority. now, they will be working closely with san francisco police in the coming days to update their security plans. we're also learning more today about a 12-year-old boy from martinez who is among those injured in the boston marathon bombings. family members say aaron hearn was hit in the thigh by some of
